The present invention relates to improvements in cash registers andrelates more particularly to cash register mechanisms for issuing salesreceipts which identify the kind of sales transaction such as, forexample, charge, C. O. D. and cash or charge and deliver sales, registerthe amount of the transaction and such other indicia as the purposedemands.

Cash registers of types heretofore known and commonly used have beenprovided with mechanisms for issuing a check or ticket Which forms acustomers receipt for a cash sale. Moreover, some of these known typesof cash registers are provided With mechanisms for entering atransaction on a sales receipt or slip which is inserted in the machineby the sales clerk.

The sales receipts are usually provided in book form with carbon papersto record the transaction in duplicate or triplicate. In recording thesale in the book, the clerk Writes the name and address of the customer,the articles purchased and the price, notes on the slip Whether it is acash, C. O. D. or charge transaction, checks the identication mark ofthe sales person and enters such other data as may be required. Thesales slips are then torn from the book and inserted in a slit in thecash register. The sale is rung up and the cash register enters thetotal amount of the sale on the sales slip and makes a duplicate entryon a continuous strip in the machine. The sales slip is then Withdrawn,a copy given to the customer, one retained as a shipping ticket if thepurchases are to be delivered, and the other is retained for auditingpurposes.

While the procedure outlined above is almost universally used in largestores, it has several disadvantages from the standpoint of eiiiciencyand accuracy. During times of large sales activity, the sales clerk intaking an order may fail to make the necessary entries in the sales bookor may merelyA note the transaction for later entry in the book andforget to enter it. Thus, entire transactions may be lost. Moreover,even when the sales book is filled out completely, if the sales slip isnot inserted in the cash register and the sale rung up, no record willbe made on the permanent record strip of the machine and thus errors areintroduced which are troublesome in auditing the accounts of the store.

An object of the present invention is to over-v come the disadvantage ofthe cash registers of the type described above by providing a multiplesales receipt issuing mechanism which eliminates the Another object ofthe invention is to provide a sales receipt issuing mechanism which, inconjunction With the printing mechanism usual in such cash registers,issues a receipt bearing the indicia necessary to identify the amount ofthe sale, and the type of sale, such as for example, charge, C. O. D.,or paid and deliver.

Another object of the invention is to provide cash register mechanismsfor issuing multiple sales receipts and as an incident to its operationpreventing a plurality of transactions with different customers frombeing recorded on the same sales slip.

Other objects of the invention will become apparent from the followingdisclosure of typical forms of devices embodying the invention.

The present application is a continuation-inpart of my copendingapplication Serial No. 326,884, filed March 30, 1940. In-accordance Withthe present invention, cash registers are provided With an auxiliarycontainer in which a continuous strip of multiple layer sales receiptforms is disposed. Means are provided for feeding said strip through aprinting mechanism and for arresting the feeding progress of said stripwhile one of the forms is disposed Within the operation zone of theprinting mechanism. The sales receipt form may be in triplicate forexample, and thus a permanent record of the transaction, a receipt forthe customer and a third receipt, which may be used as a shipping ormailing tag if desired, are all supplied with a single operation of thecash register. It will be understood, of course, that the reverse sideof the rst and second slips are coated with a carbon deposit or areotherwise arranged for duplication of the data that may be printed onone of the sheets. As en incident to the issuance of such a form, theprinting mechanism may record for example, the sales clerksidentification symbol, the date of sale, the amount of the sale, and thetype of sale made such as cash, C. O. D. or cash and delivery. Thus,when the multiple form is Withdrawn from the cash register it is onlynecessary for the clerk to enter on the face of the form the name andaddress of the person making the purchase and the name of the article orarticles purchased. This customer identication may also be made by themeans described in detail in U. S. Patent No. 2,309,645 issued to theapplicant and Franklin P. Shearer on February 2, 1943, The use of aseparate sales book therefore becomes unnecessary. As heretofore stated,means are provided for arresting the progress of the strip of multiplelayer forms while one of the forms is disposed Within the operating zoneof the printing mechanism. This arresting means is adapted to engagewith apertures in each of the forms of the strip of sales receipt formswhen said form is in a preferred disposition with relation to aperturesin said carrier plate and to withdraw from said engagement substantiallysimultaneously with frictional engagement of said strip of forms betweenpressure rolls and feed rolls whereby the Strip is fed through themachine. A timing cam, conventional in this type of machine and notshown, controls the operation of a printing roll and the strip of salesreceipt forms is adapted to pass within the operating zone of theprinting roll. The strip progress arresting means andthe means forsecuring the pressure roll in its mop-- erative position in accordancewith'the methods of the present invention are adapted to the operativecycle of said timing cam whereby arresting of one of the forms of saidstrip of forms takes place within the operative cycle of said printingroll.

The present invention will be more readily understood from the followingdescription when taken in conjunction with the Aaccompanying drawings,in which:

The present inventioni will" be described' with relation to theconventional fo'rm of cash register shown'in Fig; 1. The known parts ofsuch a cash 'register have been Vomitted from'the drawing exceptwhere ashowing has Ybeen'necessar'y to known type of cash register. This cashregister, `as shown in'Figl, ischarac'teriaed by the use of indicatingdrums I 0 vwhich 'are rotated'to indicate the value of the: saleby"meansof a plurality of 'sw'ingablelevers` `I I, correspondingto'oen'ts, tens, nanars," ten' 'dollars rand hundred dollars. `Thelevers II can beswungdownwardly"in'arcuate 'slots 'I2 in the front of'the'cashr'egisterfcasing I3 to rotate the indicating drums. This formof cash register is also provided with a lever I4 projecting forwardlythrough a slot I5 in the casing I3 by means of which the operation ofthe cash register may be altered to cause it to issue at its rear aticket I6 which is the customers receipt ior a cash transaction.

A slot I? was provided into which a sales receipt form torn from asalesbook could be in- "serted to record anydata thereonwhich may havebeen so desired when the transaction made 'was not for cash, forexample, C. O. D., charge and'deliver, etc.

The ticket I6 generally was in the form of a small slip of paper forminga portion of a roll enclosed'within the machine. Generally such a`ticket"reco'rdedonl'y a slight amount of data such as the amount of thesale and possibly a code number for the sales clerk. On the other hand.the sales receipt form which was inserted in the slot Il was generallysimilar `to the one shown in 'modied to include the'present inventionfisprovided, among other devices and -modications, with a compartmentorhopper 23 (Fig. 3) 'having a hinged or removable oover'24. yThiscompartment or hopper is preferably disposed at the rear of 'the-casingI34 in alignment with the slot Itis adapted to'hold an accordion-pleatedstrip'25 of multiple layer salesrcceipt forms such as those shown inFig. 2. This stripis adapted to be fedalong the surface of a carrierplate34 extending from an openingL in thef'rear Wall of the casing I3aligned with-a-similar opening in the compartment 23.

One of the sales receipt forms of the strip 25 is shown in Fig. 2 andcomprises an' original sheet 26,"a sheet of carbon paper2'l,v aduplicate slip 28, a second carbon sheet 29 and a triplicate sheet SI)4all assembled inthe s'upe'iposed` relationship shown toiprovide a'multi-layer sales receipt form.

It Ywill be appreciated of course, that the reversed side of'sheetsZG.-28I could be treatedwith carbon or other duplicating media and carbonsheets 27, 29 could be eliminated. As shown, spaces are provided `forthe customers name, address, and signature, for the clerksidentification number or code, for the amount o f sale and other datasuch as 'is normally required for record of'av sale.

A pair yof apert1`1'res33v are provided on thelower edge of eachf'salesreceipt form, the apertures "traversingallV the layers'of themulti-layer form.

One of the-particular-features of the "present invention is theprovision -of means for'positively arresting progress of the 'strip ofsales'receipt iorrns'while' oneof'saidnformsl is positioned to recordany transaction made onthe machinel and to automatically engagey withthe 'apertures in each of said lforms during progress of' saidstripthrough the machine during therecording of' said transaction. iThisstrip-progress#arresting means is Aadapted to positivelyengagetheapertures" 33 of one 'oi the multiple-layer sales receipt formswhen'another of saidforms; recording aprevious transaction, iswithdrawnfrom themachlne at slit l1 over table 50, and to disengage from-said aperture only on operation of releasing means which is more fullydescribed hereinafter. The strip-progress-arresting means comprises anauX- iliary plate 34--a hingedly carried on auxiliary shaft 35 by anovate-cylindraceous opening 34b.

' It will be apparent that this method of mounting auxiliary plate 34-apermits longitudinal as well as arcuate movement of the plate 34-a.Auxiliary plate 34-a carries near its free end a pair of pins 49 adaptedto continuously press against the underside of the strip of salesreceipt forms during its progress through the machine through the actionof tensioning means 45 and to enter apertures 33 of one multiple layerof said forms when the said apertures coincide with said pins 49 andwith ovate cylindraceous openings 49' in plate 34 similar to those inauxiliary plate 313-11.. By this arrangement of ovate-cylindraceousslots in plate 34 and a similar mounting for plate 34-a some slightcontinued forward movement of the strip of sales receipt forms ispermitted even after engagement of pins 49 in apertures 33. Abruptarresting of the progress of the strip is thus avoided and thestrip-progress-arresting means thus also functions as a shock absorberand prevents too abrupt stoppage of the forward progress of the strip offorms and prevents tearing of the form at the apertures 33. As may beseen more clearly in Fig. 7, the arcuate and longitudinal movement ofauxiliary plate 34-a is guided and controlled by a vertically disposedguide plate 48 which is secured to the machine wall 45 and is receivedin a slot 48 in plate 34-a. Tensioning means 45 is also attached to thisguide plate 48 and to an offset leg 41 on auxiliary plate 34-a and, aswill be seen in Fig. 3, this tensioning means is constantly urging theplate 34-a into the position shown. Auxiliary plate 34-a is alsoprovided with a vertical wing 34-d which lies adjacent the edge of plate34 at all times and serves to prevent lateral movement of the strip ofsales receipt form during its progress along the plate 34.

Auxiliary shaft 35 also carries a curved disengager 43 for thestrip-progress-arresting means and a, pair of arcuate arms 35, see Fig.7, and between the ends of these arms is supported a shaft 38 on whichare mounted spaced rollers 38 freely rotatable thereon. Disengager 43 isrotatably secured to the shaft 35 while arcuate arms 36 are rigidlymounted on shaft 35 and the disengager and arcuate arms may thusfunction independently. When the sales clerk initiates the recording ofa sale by rotation of the crank 20 or by means of the motor control bar22, the main drive shaft 2|, having eccentric cam 44 rigidly securedthereto, is caused to rotate. Driving means, conventional in this typeof machine and not shown, for type wheels 49 and the gear chainindicated generally by reference numeral 39' for feed rolls 39 arethereby set in motion.

When drive shaft 2| rotates, eccentric cam 44 which is rigidly securedthereto, rotates with it. Disengager 43, under urging of tensioningmeans 45, has its upper edge in constant contact with the periphery ofcam 44 through means hereinafter described and when the cam 44, throughrotation of shaft 2l, attains the position shown in Fig. 6, pins 49 ofthe strip-progressarresting means are withdrawn from the apertures 33permitting the strip of sales receipt forms to be moved along the plate34 by the means more fully described hereinafter. Disengager 43 isequipped with a transversely extending leg 43-a which passes beneath theauxiliary plate 34-a and engages an offset leg 41 on the underside ofplate 34-a. As stated hereinbefore, this oifset leg 41 is also engagedby tensioning means 45. Thus, when disengager 43 is rearwardly tilted bythe action of cam 44, leg 43--a acts on offset leg 41 and causesauxiliary plate 34-a to tilt downwardly and withdraw pins 49 from theapertures 33. It will be apparent that continued rotation of cam 44 willpermit auxiliary plate 34-a, through the pressure exerted by tensioningmeans 45, to again tilt upward and cause pins 49 to enter the next pairof apertures 33 when those apertures coincide with the openings in plate34.

shaft 35. During normal operation of the ma-Y chine the pressure roll 38is urged away from 39 in a timed cycle by the action of cam 13 and camarm 11i-a, as is shown partially diagrammatically in Fig. 8. Cam arm13--a is rotatably pinned to leg 31 by pin 31-a, and with the cam 13 inthe position shown has urged leg 31 and arcuate arm 36 downwardly thusovercoming the Y influence of tensioning means -a and withdrawingpressure roll 38 from its tangential contact with feed roll 39.Therefore, although feed roll 39 continues to rotate, it is ineffectivefor feeding the strip of sales receipt forms through the machine. Itwill be noted in Fig- 7 that arcuate arms 35 and leg 31 are rigidlysecured to the shaft 35 and that disengager 43 is rotatably mountedthereon.

The mechanism described in the foregoing paragraph is conventional inthe Ohrner type of cash register. The relation of this mechanism to thestrip-progress-arresting means and the disengager of the presentinvention is best seen in Fig. '7. The means 52, for securing thepressure rolls 38 out of tangential contact with feed rolls 39 is alsoshown in this View in its inoperative position. This hook member 52 isalso shown in its disengaged position in Fig. 3 and in its engagedposition in Fig. 5, engagement in this latter ligure having beenattained by manual manipulation of the lever 65. Both the manual and theautomatic means for engaging and for disengaging hook member 52 aredescribed hereinafter.

In the conventional operation of a machine of the type described areceipt ticket l5 would be issued to a customer when the transactionmade was for cash. In this type of device the lever 66 controls theprinting and ticket issuing mechanism and is normally brought to thelower position when a receipt ticket I6 is to be issued. In accordancewith the present invention the ma*- chine is altered to includemechanism for locking the lever 65 in recept-ticket-issuing positionwhen it is desired to issue a ticket while normally retaining said lever66 in the upper position by tensioning means 66--a where no ticket i6Will issue. Since the feed roll 39 rotates however, with any operationof the machine, the present invention also provides a means to renderthe feed roll 39 ineffective during a cash transac- ...ZASZQQM tion; themechanism being-shownin Figs. 3vand :4 `with an enlarged showingvin4l"ig.,5. To Vac- ;complish this a shaft -5I -is provided extendingtransversely of the frontof the machine as shown in Fig. 4. This shaftis provided with a hook 52 lwhich is adapted to engage .the shaftcarrying pressure rollers `3 8, 38 and .thus overcoming'the effectzoftensioningrneans 13S-a secured to leg 1'31. .Pressure iroller .38 is:thus gprevented from `frictionally engaging ,the strip of sales receipt:forms l between itself Aand feed roll '395and `the feedfrollisrenderedineiective. Thus, 'during voperationpf the machineto issueagcashreceipt -.ticket I6,1the .strip '25 does not progress :through:themachine even-when strip-progress-arresting pins 49 are withdrawnduring such operation. ,As rnayalso'be ,seengin Figs. .4: and'5,'the:shaft 5 I has an elongated 1ever;5 3 at its right-hand end theupper rend ofsaid'lever'beinguided1in a ,slot 5.4`by a guide memberg-which isJXed `to :and :suitably spaced from partition 56 of :the:machine casingby spacerimeans.

Thus, if thedevice is inadvertently set for a cash transaction, the levers r|56 andI4 may vbe squeezed together and the hook 62 is rotated out ofengagement with the pin B4 whereupon thelever 65 swings upwardlyreleasingpressure roll 38 and permitting issueof a form from the lstripof sales receipt forms 25. Release is also accomplished automatically`by means of the cam l44. Hook member 62 is provided with a rearwardlyextending lever arm 1I, the end of which'engages the cam 44 when the camrotates causing the hook member 62 to rock counterclockwise and becomedisengaged from pin 64. Itwill be app-arent from the foregoingdescription and from the drawings that cam member 44 during asinglerevolution then serves to release the strip progress arresting means,hereinafter referred to as form registering and detent means, vbycausingwithdrawal of the pins 49 in auxiliary plate 34-a and also serves tocause pressure roll retaining means 52 to resumean inoperative position.The strip progress arresting means is referred to hereinafter in theappended claims as form registering and detent means.

Although my invention has been described in connection with a preferredembodiment, it will -be observed that variations and modifications maybe resorted to, as those skilled in the art will understand. Forexample, although my invention has been described with respect to` anembodiment applicable for attachment to an Ohmer class 8000 cashregister, it will be realized that .arresting means and functioningtherewith to attain the same results in other ways.

These, as wellas other variations and modifications, are to beyconsidered within the scope of the present specification and withinthepurview of the appended claims.
